Transmission-band lining



UNITED STATES "li iii l. tl

Application. filed August it,

To ai? infront fait may concern.'

Re it known that lt, lid/'rentinl-l. Hum, a citizen ot the Hlnited States, residing; at Patersonl in the county ol Passaic and tii'tate oit New Jersey, have invented new and usetul lniproveinents in 'llransmissionfldand Tliiiiinis, ol` which the following` is a speciiif cation.

This invention relates to band lining and to the meth-od oi2 making; the same, an object beine' to provide a lining` Which is especiall) 7 adapted :tor automobile transmissions of the planetary type.

ln mechanisms of this character it is desirable to obtain the maximum amount ot bearingI between the lining` and the drum and as these drums (as in the Ford automobile) are placed close together, this is not possible With the round edge type ot lining nonr in use. Furthen in order to provide for long; Wear it is essential that a manimuin number of threads be used in a Woven lalfnfic linfr and that the fabric be ot a touejh yet pliable character.

lltleretotore, Woven band linings `for this purpose have been Woven of a thickness and Width. oit the finished produca With a result that the itabric is oft a more or' less loose `Weave irrespective ot the manner in which the fabric Woven. In the present invention l'iowever, the 'Fabric is woven to a greater thickness than the Finished [noduch which perini ot' the use of an increased number of threads, and this tab i is passed between rollers and pressed to the desired thickness and Width, that a relatively hard compact lining results.

liVith the above and other objects in View, the invention furtlier includes the `followinna novel ileatiu'es and details ot construe ti om to be hereinafter more tally described, illustrated in the accompanying' drawing-s and pointed out in 'the appended claims.

in the drawings:-

liigure il is an elevation ol? a transmission band with the lining applied thereto,

Figure 2 is an enlarged fragmentary lon {xitudinal section illustrating the character ot the Weave.

Fipuire 3 is a transverse sectional view ot the same.

Figure l is a diagrammatic vievv illustrating the cross sectional shape of the fabric after weaving;f and before pressing.

igure 5 a similar vievv showingI the iiabric pressed to the required thickness and ivi d th l-lilnure 5 is a iliragiinicntarr cross sectional view oit the prior art shoivino; a round cdpge lininnl applied to a transmission band.

liie'ure 'i is a similar View showing; a square edge lining; and illustratinnl the increased bearing surface obtained thereby. i

liiejterrino' to the drawings i n detail. Wlierein like characters oit reference denote corresponding parts, the 'fabric lining;- is illustrated as termed ot' a plurality of Warp and Wool threads Woven so as to provide opposite relatively wide surfaces 'l0 and square edges l1.

The fabric is ivoren to a greater thickness than the thickness of the finished lining, being; reduced to the proper thickness and Width by pressureEJ such as passim: it between pressure rollers lf2 and 13. The linished lining is then ot the proper thickness and is ot the saine Width as the band lll; and drum 15 With which it is used lt will be noted by comparison oit liligi-- ures G and 7 of the drawings that the lin ingwhich is indicated at 1G is of the same width as the Width oit the band and drum, while the round edpge liniup,P indicated at .lliv in Figure G is also oit the same Width but the bcarin surface oit the linings; is less than the lining: "i6 due to the rounded ednjes. ln addition bjv subjecting' the Woven lining; to pressure ated a t" bt compact lin inn is provi ded which, on up" to its oi thickness naarv coni i an i creased nui ber oli' threads. The lite ot the liniiniM thus in a teri alljr lengthen ed..

In order to insure proper absorption ot oil. the ends ott the linup; are raveled as inH dicated at ld in lliu'ure 'l ot the draWindsM so that the threads will absorb oil fitter the manner ot a wich'A and the liuinp; thus remain properlyv luluficated ln addition to providing; an increased. amount oft materiah the i n creased number oi threads ot the Woven linien? also provides `For an increased absorption of lulnican'h so that the drums are ltept properly'v lubriy cated and Wear upon the lining; reduced as 'Well as tendency7 of the band I'o chatter. Further, the increase of material after the lining is conuoressed adds bodv and stability to the lining; and reinforces the banch so that the latter will be maintained in proper circular formation to grip the drinn evenly 'iti Sti

The invention is snseeptibie of various Changes in its form, proportions :find minor details or construction and the rightis herein reserved to make such changes ns properliT fall Within the scope ei' the nppended claims.

Having described the invention what is claimed is:-

l. A. transmission lining fornied ot :1, `vwoven fabriel having square side edges sub stnntinlly 'flush with the side eil; C oi: the, transmission drum and the band to which it is applied, and having .its ends raveled to provide for n ready absorption of lnbricant.

method of mailling woven liningr fm` bands Consisting in forming a strip o1 woven i'nln'ir o. :t greater thickness than tlnl thickness of the finished liningr :md containing only the Warp and weft yarns and subjecting it to pressure to form a ronipzwt; strip of the desired thickness sind width.

3. A method of making Woven lining for bands consisting' in forming :i strip ofi Woven rubric of zi lgreater thickness thun the thickness of the finished lining :ind eontaiiningr onlj,v the warp and weft yarns und subjecti in it to pressure to forni :i compnet strip oi the l/lfmired thiehness and width :1nd rzirelling its ends to provide for a ready absorption oi lubricant.
